IMPROVEZD MACHINE FOR IE'INISHING- GALVANIZD TACKS.

'l'he Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern.:

Be it known that we, RUSSELL HATHAWAY, Jr., and JOEL D. S'nn'rson, of Fair Haven, in the county of Bristol, and in the State of Massachusetts, have invented certain new and useful Improvements in Machine for ,Trimming and Galvanizing Tacks, Nails, 850.; and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

rJlhe nature of our invention consists in the construction and arrangement of a machine to be used for the pnrpose of throwing off superfiuous metal from tacks, nails, and otherl articles that have been covered with tin, lead, zinc, Sto.

lu order to enable others skilled in the art to which our invention appertains, to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Fignre lis a Vertical section, and

Figure 2, a plan view. A reprcsents the frame of the machine, the top of which is provided with a circular opening of suitable size.

In this opening is secured a metal cylinder, B, which extends a suitable distauce above and below the top of the frame A, said cylinder being, however, open both at top and bottom.

'On the rear side of the frame A is titted a metal plate, O, which extends a certain distance below the lower edge of the cylinder B.

An inclined metal plate, D, extends'from the real' of the frame forward, and projects iu front of the frame, saidplate being turned up, so as to lform sides,

rear edge of the plate F and the plate D. There is' also 'a space left between the lower rear edge of the plate F and the upper rear edge of theplate D, as shown in fig. 1. The plate F is also provided with turned-up sides, which, however, exteud downward entirely to the plate Through the sides of the frame A is placed a shaft, I, which, on one end outside of the frame, is provided lwith a pulley, G, from which pulley a belt will lead to some machinery close at hand.

'cross-bar, K, inside of the cylinder, in such a manner that the shaft will be exactly in the centre of said cylinder.

On the shaft L, above the cross-bar K, is placed a disk, M, which has a flange,l, pi'ojecting upward across its centre, and is so placed that it shall be immediately uider a 'cross-bar, N, which is secured to the upper edges of the cylinder B, across its centre.

To the centre of the cross-bar N is secured a hopper, O, the cross-bar being provided with a hole, or opening, to allow any articles placed in said hopper to pass through.

i' Articles, such as .taoks, nails, &c., having been put into molten metal, require to be-thrown out violently against some surface, to free them from superfluous por.- tion Vthat adheres. .By dropping such articles, taken from the moltcn metal, downQ the hopper O, they'fall ,on the disk M, which is driven at a high rate of speed,

and are thrown off violently by the centrifugal force imparted to them by the revolving disk; Having thus fully described our invention, What we claim as. new, and desire to secure by Letters Patent, is-- l 1. A machine so constructed that articlesthat hav been dipped in tin, lead, zinc, 8m., may bc frecd from the supertluous metal adhering to them, by being 'thrown violently against some surface, substantially Wiinesses:
